BURNER.

Application flled' August 23, 1923. Serial No. 659,014..

To all whom it may concern:

Be it known that I, AoHiLLn KAIS, a citizen of the United States ofAmerica, and a resident of Highland Park, in the county of ,u Wayne andState of Michigan, have invented a new and Improved .Burner, of whichthe following is a description.

My invention relates to a liquid fuel burner and more particularly isintended as an improvement on the invention forming the subject matterof an application filed by Kaiserman & Zaugg, April 15, 1921, SerialNumber 461515 and is also in some repects an improvement on theinvention forming the subject matter of an application for patent filedby me June 22, 1923, Serial Number 647113.

The general object of the present invention is to improve burners of thetype shown in my aforenamed applications whereby 'to produce a cleanefi'ective flame well adapted for use in industrial furnaces and providea burner eflicient for use in country homes where gas or electricity isnot available. 1

The nature of the present improvements and their distinctive featuresand advantages can best he explained in connection with a specificdescription of the illustrated example of the invention as hereinaftergiven.

Reference is to be had to the accompanying drawings forming a part ofthis specification, it being understood that the drawings are merelyillustrative of one example of the invention.

Figure 10 shows an end elevation of the gas burner attachment;

Figure 11 is a detail in vertical section as indicated by the line11-11, Figure 9.

In carrying out my invention in accordance with the illustrated examplea steam generator 15 is provided having ,a water inlet 1.15 and atubular double-walled steam chamber 16 at the top, the interior of whichconstitutes a combustion chamber 17. The assemblage comprising the steamgenerator 15, steam chamber or dome 16, and combustion chamber 17, isessentially that disclosed in my first-mentioned. application and needsno detail explanation herein. From the steam chamber 16 leads a steamoutlet pipe 18 communicating by a pipe 19 (Figure 2) with a four-waycross 20, a branch of which connects by pipe 121 with a pressure gage21. Another branch constitutes a steam outlet leading through a valve 22and a pipe 23 (Figure 2) leads the steam to an atomizer head designatedgenerally by the numeral 24.

An oil pipe 25 leads also to the atomizer head 24 at the under sidethereof, said oil pipe connecting by its inlet 125 with an oil levelcontrol reservoir 26, said reservoir and its valve controllingappurtenances being disclosed in my second-mentioned application, thecontrol means being slightly modis5 fied as hereinafter explained. Thenumeral 126 indicates an oil supply pipe loading to the reservoir 26. v

A nozzle 27 is disposed in a fitting 28 in the atomizer head no by aport 29 with the and therefore with the steam pipe 23. The inlet end ofthe nozzle 27 is controlled by a needle valve 30. The fitting 28 issuit-ably held in place as by a set screw 31.

Communicating with the head 24 also at a side thereof is an air pipe 32which in 24 and communicates interior of said head practice maybeconnected with a hand-operated air'pump, the purpose of which willappear hereinafter.

The steam and air nozzle 27 discharges to aburner nozzle 33 at one endof the com bustion'chamber 17, 'there being provided an inclined drippan or spout 34 at the front of said burner 33 to conduct drip oil tothe I-: provide a water feed control device control device'36 and awater outlet pipe 39 leads from said device 36, both the inlet and.foutle't being abovethe-diaphragm 37. The

outlet pipe 39 connects with the inlet pipe '115'of-the steam generator15. A waterport said valve 41 being pipe 43 from the cross 20.

40 connects the inlet'pipe 38 with the outlet 20 pipe 39-and said port40 is controlled by a check valve 41 here shown as a ball valve, adaptedto be engaged by a lift pin .141 on chamber 42 below the diaphragm 37communicates with the steam line'by a branch steam pressure develops inthe chamber 42 the steam will back up through the branch '43,"cross 20,pipes 19 and 18, and the back pressure developed will result in loweringthe water level in the generator 15 and cause the water to back upthrough the inlet 115, pipe 39, port and inlet pipe 38. Thus, thepressure on the diaphragm at the water side and the steam side will beso maintained that there will be a slight preponderance of presa sure onthe steam side ofthe diaphragm 37 sufficient to maintain the valve 41open to the flow of water of the generator 15 but anyexcessivepreponderance of pressure on the steam side of the diaphragm will bebalanced by theback pressure of the steam on the {water circuit andtherefore on the diaphragm '37. At the lower end of port 40 is valve 62onthe diaphragm 37 and a spring 63 at the steam side of the diaphragmpresses against said valve tending to ba. ance the pressure of the wateron the diaphragm. The valve 62 has two flat} sides 64 so that a movementof the valve to the port 40 will not totally close said port. The valvelift pin 141 has guided movement in a socket on the upper end of avertical spindle 66 adapted to turn in the bottom of the body of thecontrol device 36: A spring 67 is coiled about the spindle 66 to pressit against a nut 68 to re ulate the tension of the spring.

he spindle 66 may be turned to thus turn the pin 141 for re ula-tin'gtheinlet flow past the-ball check va ve 41' to start the flow of waterand maintain said valve 41 open until steam pressure is suflicient'tohold the valve in the open position. The nut'68 has teeth 69 and a lockspring secured to the body of the control device 36 has a rib 71adaptthe diaphragm 37. The" If excessiveed to engage between teeth ofthe nut 68 to hold the nut in adjusted position.

In my second-mentioned application, Serial Number 647,113 the oil levelcontrol reservoir 26 is fully described as including a,

valve of the reservoir 26 in the present in-- stance is indicated by thenumeral 46. The numeral 47 indicates an overflow duct from the reservoir26 to a pipe 48 discharging to drip pan 49 suspended on a lever 50 asfully described in my said second application. Said lever 50 is hereshown fulcrumedl at 51 on a bracket 52 on reservoir 26 and one arm ofthe lever has a. toe 53 adapted to engage and rub over a toe 54 on alever 55 disposed beneath a vertically movable in 56 about which iscoiled a spring 57. n spindle 57 above the reservoir 26 is a yoke 58provided with an upstandin pin 59 to receive one end of a coupling bar60, the opposite end of which is secured by nuts 61 to the valve stem46. Thus, upon the overflow of oil into the dri pan 49 from reservoir26, the lever 50' wil rock downwardly, and its toe 53 will. engage thetoe 54 of lever 55 and rock said ever 55 in a manner to lift the in 56thereby throu h yoke 58 and coupling ar 60 lifting the va ve 46 andclosing said valve, thereby cuttin off the inflow of oil to.reservoir 26as fufiy described in my application No. 647,113. The feature of thepresent invention in so far as the same relates to the reservoir 26 andits appurtenances, resides essentially in the elements 53, 54, 55 foroperating the pin 56 in a direct and eflicient manner.

A sleeve 72 is threaded onto the valve 30 and a lever 73 has a. crosshead fulcrumcd as at 74 on a bracket 75 appurtenant to the atomizer head24. One arm 76 of lever 73 is pivoted to the sleeve 72. connects by awire 77 and other suitable connections with a thermostatic device (notshown) on the furnace so that the lever will be rocked under excessiveheat in the furnace A, in connection with which the burner assemblage isinstalled. The rocking of the lever 73 will thro 11 its arm 76 cause thesleeve 72 to move t e valve 30 to the closed position for cutting offthe flow of steam or air from port 29, thereby destroying the suction onthe oil pipe 25. The second cross arm 78 on lever 73 has secured theretoone end of a connecting bar 79, the opposite end of which connects withone arm of The lever 73 an essentially T-shaped lever 80, the other armof which has secured thereto a valve stem 8lhaving a valve 82controlling an air inlet port 83 through which air is directed.

to an oil passage 84 leading to the burner nozzle 33 from a vacuumchamber 85 at the upper end of the oil pipe 25. The arm 78 of lever 73also pivotally supports a lever 86 adapted to be manually operated inany suitable manner, the connecting bar 79 for operating the air valve82 is carried by the lever 86 instead of by the arm 78 of lever 73 sothat said connecting bar 79 will be operated by locking of the lever 73but may be manually operated by the lever 86. The lever 86 has a hook 87adapted to engage against the shoulder 88 on the bracket 7 5 to limitthe movement of the arm 78 and lever 86 in one direction. A screw 89 inthe bracket 75 limits the movement ofthe hook 87 in the other directionand thus limits the movements of the levers 73 and 86.

In my present invention the steam genera-tor is supported as follows:The tubular steam chamber 16 is provided within the combustion chamber17 thereof" with a. frame 90 as best seen in Figure 4, the upper portionof which is in the form of a separate section 91. Said frame fits snuglywithin 1 -the combustion chamber 17 against the inner wall of the steamchamber 16. The ends of the body of the frame 90 and of its separatesection 91 jointly receive fastener screw bolts 92 which pass into thejoint between the main and separate sections and through the front ofatomizer head 24. The oil drip pan 34 is integral with the frame 90. Thescrew bolts 92 have nuts 93 (Figure 2) which may be tightened up againstthe flange 94 of head 24. The lower portion of the generator 15 which iscylindrical is embraced by a clamp band 95 having separated terminals 96through which a bolt 97 passes to tighten the clamp band 95 on thegenerator 15. The clamp band 95 is formed with a pair of eyes or sleeves98 which rest on set collars 99 adj ustably secured by their set screws100 on posts 101 rising from the base plate 102.

A combined ignition gas burner and pilot light assemblage provided asfollows: A gas chamber 103 has a dependim inlet fitting 104 controlledby a gas coci 105 and adapted to receive a hose or other gas supply pipe106. Rising from the chamber 103 and communicating with it are two gaspipes 107 each having an elbow 108 at the top carrying a forwardlydisposed burner nozzle 109 formed with a row of jet orifices 110-in theupper side at the top thereof. The flow of gas from the inlet fitting104 to the chamber 103 is controlled by avalve 111 advanta:

geously in the form of a threaded needle valve passing through thethreaded stufiing box 112 manually operable to regulate the flow of gasto the respective pipes 107. Leading laterally from the dependingauxlliary chamber 113 integral with the chamber 103 below the valve 111is a lateral nipple 114 with which by-pass gas pipes 115 are connected,the upper ends of said pipes 115 connecting with elbows 116. Leadingforwardly from the elbows 116 through the burners 109 centrally thereinare pilot light tubes 117 terminating forwardly of bracing partitions118 in said burners 109 near the front ends. The chamber 103 at theunder side is formed with air inlet openings 119 for the admission ofair to saidchamber to mix with the gas rising in the pipes 107 after themanner of a Bunsen burner. The burners 109 rest slidably on hook-shapedlateral brackets 120 on atomizer head 24.

The arrangement of the burner assem blage is such that it may be movedforward t or back on the brackets 119 and through the front end of thehead 24 to position the gas burners 109 with their forward endsadjacent. the forward end of the combustion chamber 17 or in therearward position in said chamber.

The numeral 120 indicates a weight 17 3 to resist movement of lever 73upon a predetermined pull when exerted on the element 77.

'When the burner is in use steam will be generated in the steamgenerator 15 by the heat of the burner and'will pass outward throughpipe 18 to pipe 19 and to valve 20 where it divides to pass to gage 21,by pipe 43 to the water feed control device 36, and by pipe 23 toatomizer head 24. Steam passing into the head 24 is directed forwardlypast valve 30 through nozzle 27 to burner nozzle 33 and to combustionchamber 17. The action of the steam in passing from nozzle 27 willcreate a vacuum in port 84 and vacuum chamber 85 associated with oilinlet pipe 25, and thus by ejector action drawing the oil along with thesteam to the burner nozzle 33. The valve 82 when opened either by manualoperation through the medium of lever 86, rod 79 and lever 80, or bythermostatic action on the element 77, will admit air in greater orlessvolumeto the port 84 thus reducing the vacuum in chamber 85 and therebyreducing the feed of fuel from pipe 25 by the action of nozzle 27. Inthe absence of steam air under pressure from a hand pump and directedthrough pipe 32 will have the same effect as the steam in atomizing thefuel passing through nozzle 33. When thehand pump and air therefrom areutilized the flame at the burner 33 is manually ignited. When steam fromthe nozzle 27 is utilized to atomize the oil, the gas burner and pilotlight assemblage of Figures 9 to 11 is utilized to ignite the flame andproduce an initial heat for starting the burner to generate the steam ingenerator '15.

I would state in conclusion that while the illustrated exampleconstitutes a practical embodiment of my invention, I do not limitmyself strictly to the exact details herein illustrated, since,manifestly, 'th'esame can be considerably varied without departure fromthe spirit of the invention as defined in the appended claims.
